    摘要： An apparatus (100, 1001) comprises an image capturing device (110), a light emitting device (112) for illuminating an object to be captured by the image capturing device (110), a visual guide (114) to guide a user to aim the apparatus (100, 1001) at a target authentication device (140), and a processor (102). The visual guide (114) is devised such that when the apparatus (100, 1001) is aimed at the target authentication device (140) following guidance of the visual guide (114), the brightness levels on an image of the target authentication device (140) captured by the image capturing device (110) while under illumination of the light emitting device (112) are within a predetermined range of brightness levels to facilitate verification of authenticity with reference to the captured image of the target authentication device (140).

    摘要： An indicia reading terminal is disclosed that eliminates unwanted flickering effects in an illuminated screen reading mode, among other advantageous features. The indicia reading terminal, in response to a screen reading signal, is operative to activate a screen reading cycle. In the screen reading cycle, an imaging subsystem is activated at least once at the same time that an illumination subsystem is activated for one of a plurality of active illumination periods, for a first illuminated exposure period. The imaging subsystem is activated at least once while the illumination subsystem is not activated, for a first unilluminated exposure period, which is longer than the first illuminated exposure period. An aimer subsystem is activated for a plurality of active aimer periods when neither the imaging subsystem or the illumination subsystem is activated, wherein intervals of time between the active aimer periods are equal, within nominal tolerances.

    摘要： Methods are disclosed for triggering a source of visible light in connection with a data reader in response to a sensed proximity of an item. In one configuration, a data reader includes an imaging reader, such as a CMOS imager, that is sensitive to both infrared illumination and visible light. The imaging reader may be operable to read a symbol, such as a barcode or other optical code, via reflected infrared illumination, reflected visible light, or both. When characteristics of reflected illumination received by the imaging reader indicate the presence or movement of an item in the visible scan zone, the visible light source may be triggered to illuminate the item and thereby facilitate reading of the symbol using the same imaging reader as is used to sense the presence of the item. The visible light source may also be triggered to provide visual feedback.
